If it reports Error 26, then you've the Descriptor Region locked and you can downgrade only using an external EEprom SPI Flash programmer.

Okay now it said:

Error 451: The host CPU does not have write access to the target flash area. To enable write access for this operation you must modify the descriptor settings to give host access to this region. FPT Operation Failed.

Doesn't look good.

It is reporting what I've said before, your Descriptor Region is locked. It's very strange that you're experiencing such issues as other users trying the same MEI firmware on the same chipset, have no problems at all.I think you should better try to do a Clear CMOS and trying to set up bios settings and boot into Windows and see if your LAN works.

Well i've done it multiple times already while trying 4 different BIOS versions. I also tried removing and reinstalling the drivers. Does this mean my ethernet is bricked completely?

No you haven't bricked anything. Maybe there is some incompatibility between the MEI Firmware and the LAN, but if it worked before flashing the modded bios, it can't suddenly stopto work.

You could try to boot a linux live distro, like Parted Magic and see if the LAN works. If it does, then it's a Windows issue strictly related to the MEI firmware.

Okay I tried to boot Lubuntu live usb and it still didn't work. I tried wifi usb dongle just in case and that one worked so the problem is indeed in the ethernet controller and not in the linux distro.
